Music fans are wise to be leery when they see phrases like "all-original lineup" and "long-anticipated reunion tour" followed by that cracked-out whore of the punctuation world -- the exclamation point. We all know what she's hiding: The fact that the band members are broke and temporarily putting aside mutual hatred for quick cash.

Here's a rundown of the essential albums available online and in record stores today:

This week, Eminem's new single, "3 A.M.," leaked -- as did a teaser video for the gory song, along with more details about his May 19 record, Relapse. Meanwhile, SPIN reviewed Green Day's 21st Century Breakdown (May 15), as the band defended their classic-rock ambitions and punk rock roots.

Dinosaur Jr. bassist Lou Barlow is a man of his word.

Dinosaur Jr. influenced Nirvana and laid the foundation for the grunge movement -- and now, with the original lineup reunited after a 16-year split, the trio are returning to their seminal, punk-meets-classic rock sound with their new album, Farm, out June 23. "It's totally old school," bassist Lou Barlow tells SPIN.com. "[The album] sounds like our first three."
